Before we discuss the design trends and products related to architectural decorative glass, the following slides present a glossary of key terms that are used in the industry that you may find helpful.






< >

Glossary of Key Terms

• Annealing – A process of slowly cooling hot glass to relieve internal stresses and strengthen it.

• Anti-Reflective Glass – A dielectric, thin-film coating applied to an optical surface in order to reduce the optical reflectivity in a certain wavelength range.

• Back-Painted – Glass that has been painted a flat color on one side of the surface.

• Beveling – Edge finishing flat glass with a beveled angle.

• Ceramic Frit – A ceramic composition fused to glass through tempering.

• CNC Cutting Line – A process used in the manufacturing sector that involves the use of computers to control the line of cutting and improve precision.

• Cut Sizes – Glass cut to a specific length and width.• Drilling – Cut notches, make holes or shapes in glass, usually done with a CNC computer to automate the process.

• Edge Polishing – To machine the edge of the glass to produce a high polish with a flat edge and two arisses (small, angled edges).

• Fabrication – Manufacturing process in which an item is made (fabricated) from raw or semi-finished materials instead of being assembled from scratch.






< >


• Flat Glass – A general term to describe float glass or sheet glass.

• Glass – A hard, brittle substance, typically transparent or translucent, made by fusing sand with soda, lime, and sometimes other ingredients and cooling rapidly.

• Heat Resisting – Glass that is heat-treated or leached to remove alkali so that it withstands high heat and sudden cooling without shattering.

• Heat Strengthened – Glass that has been processed through a tempering furnace to alter its strength characteristics; usually flat or bent glass that has been heat-treated to have a surface compression between 3,500 and 7,500 psi (24 to 52 MPa), typically two times stronger than annealed glass.

• Laminated Glass – A type of safety glass that holds together when shattered; pieces are held in place by an interlayer, typically of polyvinyl butyral (PVB) or ethylene-vinyl acetate (EVA), between two or more layers of glass.

• Low-Iron Glass – Glass with a low iron content that has a higher visible transmittance and thus a greater ability to collect solar energy, offered in float or satin etched glass.

• Magnetic Glass – Glass with a steel sheet attached to the back of a flat glass surface making it magnetic.

• Mirrored Glass – Glass that has a reflective surface on one side.






< >


• Miter – A joint made between two pieces of glass at an angle of 90°, such that the line of junction bisects this angle.

• Monolithic – Another name for annealed glass.

• Patterned Glass – A type of glass used to control light, obscure visual detail for privacy, or provide decorative effects.

• Reflective Glass – Glass that has been treated with a metallic coating that allows it to reflect heat.

• Satin-Etched – Glass that has been chemically treated to give it a satin or frosted finish, on one or two sides.

• Seam – To grind or sand the sharp edges of a piece of glass, usually with an abrasive belt, wet or dry.

• Silkscreen – Transferring an image to the glass by pressing ink through a screen and then processing it through a horizontal tempering furnace.

• Tempered Glass – A process of controlled thermal or chemical treatments that puts outer surfaces into compression and inner surfaces into tension and makes the glass four to five times stronger and safer than annealed or untreated glass. As a result, tempered glass is less likely to experience a thermal break and, if it does break, it breaks into many small pieces, thereby reducing the chance of injury.

• Tinted Glass – Coloring glass during the manufacturing process to reduce the transmission of light and solar energy.






< >


• Shading Coefficient – Measures the total amount of heat passing through the glazing compared with that through a single clear glass.1

• Solar Heat Gain – Second major energy-performance characteristic of windows is the ability to control solar heat gain through glazing. Significant factor in determining the cooling load of many commercial buildings.2

• Light Transmittance – The proportion of visible light at near normal incidence that is transmitted through the glass.3

• Safety Glazing – Reduces the risk of injury by tempering or laminating glass.4

< >

Digital Printing

Digital printing enables greater architectural performance, thereby enhancing functionality for your interior and exterior glass designs. For example, digitally-printed glass can provide privacy, glare control, and improved daylighting to reduce the need for artificial lighting. For solar gain control, digitally-printed glass products can be insulated using high-performance low-e coatings.

Laminated applications include:• overhead glazing• fall-out prevention• hurricane resistance, and• blast resistance.

Digital printing can be combined with other processes and complex fabrication techniques, such as drilling for point-supported installation.






< >

Digital Printing

Digital printing allows for the combination of patterns, color, and transparencies to bring the most creative visions to life.

The digital printing process begins with the creation of an image using any current graphic design program. Employing a digital printer with ceramic frit inks, the image is printed directly onto the glass surface. Colors are blended digitally on the glass, negating batch mixing.






< >

Digital Printing

The image is then baked into the glass through the process of tempering (left image), providing a durable glass surface that is resistant to scratching, UV light, and weathering. Prior to leaving the factory, digitally-printed glass products are inspected to ensure there are no imperfections in the image.






< >

Applications






< >

Interior Applications

Product AttributesInterior applications of decorative glass are typically non-structural. Overall, the usage of decorative glass is to enhance the visual interest of the interior space, using colors, images, patterns, textures, and light transmission. Generally, monolithic glass thickness is 3/16" or greater for interior applications.

PerformanceDecorative glass for interior applications must be fully tempered (and in some cases, laminated) to meet code and safety requirements.






< >

Exterior Applications

Product AttributesThe use of decorative glass for exterior applications enhances the aesthetic value of a building, and its use is on the rise. Exterior applications may be structural or non-structural. In the past, the only available colors of glass were clear, bronze, gray, and light green. Today, designers have the entire color spectrum at their fingertips, so accent pieces can be produced to meet the look and style specified. Pattern pieces can give the appearance of the building a whole new dimension, while at the same time improving performance and reducing glare.

PerformanceDecorative glass for exterior applications can be monolithic or insulated. It is always fully tempered and can be laminated to meet safety and code requirements.






< >

Glazing Systems

Decorative glass can be used for a variety of interior and exterior glazing systems, including:• entrances• window walls• storefronts• curtain walls• glass doors, and• custom systems.

Glass for glazing systems may be monolithic (typically in thicknesses up to 1") or laminated (in thicknesses greater than 1") or may be part of insulating glass units.

In the majority of cases, decorative glass fits the same way into the various framing systems as non-decorative glass.






< >

Interior Walls & Partitions

The use of decorative glass panels for walls and partitions is a popular trend in interior design.

In a New York City public school, a public art piece, featuring decorative glass panels, plays with concepts of light, transparency, and color. Here, the digitally-printed tree reflection creates the illusion of natural light in a windowless space.

This lovely wall surface in the Memorial Sloan Kettering Cancer Center in West Harrison, NY was created using a four-surface digital printing process on 7/16" quadruple-laminated glass.






< >

Art

Decorative glass can be used to create eye-catching artwork in any size, shape, or color for residential and commercial markets. As part of the $26 million renovation at New York’s historic Penn Plaza, this beautiful artwork was created by digitally printing a historic image in sepia tones on 84" X 128" low-iron, tempered glass.

31 Penn Plaza, New York, NY






< >

Signage

Signage is one of the fastest growing interior applications for decorative glass. For many design and build professionals, glass has become the material of choice for displaying corporate signage, logos, lobby directories, and wayfinding signs.

This example of decorative glass features an attractive sign with the university’s name and logo made of four pieces of 3/8" one-sided, anti-reflective, low-iron, digitally-printed glass.

Catholic University, Washington, DC






< >

Railings

Glass railings will make a space look modern and extraordinary. They may be used for exterior and interior applications and can be combined with other materials, such as wood or metal, to create a unique look.

The 1" laminated glass panels on these railings were digitally printed with a continuous, non-repeating pattern, designed to complement an original sculpture hanging above the staircase.

Staircase and sculpture, Los Angeles, CA






< >

Storefronts

Decorative glass is used to create storefronts that complement the architectural style of the building and provide an aesthetically pleasing, inviting look.

Harlem Hospital Center, New York City, NY

The curtain wall of this 13,000-sq.-ft. hospital in New York City features 429 completely unique, laminated, insulated, digitally-printed pieces of glass that come together in a modern work of art that pays homage to historic murals. Careful testing of opacity levels with the digital printing system controls light levels to maintain privacy, while creating a spectacular glow, both inside and out.






< >

Newark Liberty International Airport, Newark, NY

For the Newark Liberty International Airport, Terminal B, 13/16"-thick laminated, tempered, low-iron glass was used for the panels above the check-in area. The panels were printed in a true fade using direct-to-glass printing technology for a subtle effect that provides privacy, while allowing passengers to see activity above. This combination proved to be useful at the airport where both style and safety are essential to the airport’s overall design.






< >

New York-Presbyterian Hospital, New York City, NY

For this hospital in New York City, 150 linear feet of 3/4" laminated glass was used to create an elegant canopy decorated with a deceptively delicate pattern. Individual striations grow more slender as they move outwards across each piece of glass, controlling shade while subtly drawing people forward into the light. Printing white ink and etching make this unique patterning possible, where silkscreening would have been prohibitively expensive.

Panels of wood imported from Africa are one of the key interior design elements at Tata Hall; the architects were hoping to find a way to use the beautiful wood grain pattern on the exterior of the building.

Working closely with the designers, contractors, and glass manufacturer, a stunning glass wall was created with a digitally-printed custom pattern that matches the exotic wood grain.

The glass wall extends the beauty of the interior finish to the building exterior and provides a dramatic architectural statement that fulfills all functional and aesthetic requirements.

The glass wall is comprised of 144 pieces of 1-5/16" and 1-7/8" thick, tempered, laminated IG units with low-e coating on low-iron glass.

The building façade of this 75,000-sq.-ft. academic center features 128 precision fabricated, “K” shaped fins of 9/16", low-iron, laminated, digitally-printed glass.

Precision fabrication was important in this project to ensure all pieces would line up during lamination. Each piece was printed with a custom opacity to achieve the desired white, pixilated pattern.
